What does Investment Treaty Arbitration mean?
investment treaty arbitration is investor–state dispute settlement (ISDS) in which a foreign investor brings arbitration claims against a respondent state or state entity for alleged breaches of protections in a bilateral investment treaty (BIT) or a multilateral treaty (such as the Energy Charter Treaty). It is a descriptive term used across international practice rather than one defined by UK or Irish legislation or case law. Key features include consent to arbitrate given by the state in the treaty; claims typically alleging breach of fair and equitable treatment, unlawful expropriation, most‑favoured‑nation or national treatment. Proceedings are commonly under the ICSID Convention or ad hoc under UNCITRAL Rules (with SCC/ICC used less often). Remedies are primarily monetary damages. ICSID awards are enforceable pursuant to the ICSID Convention; non‑ICSID awards are generally enforced under the New York Convention and relevant arbitration legislation. Issues of jurisdiction, admissibility, cooling‑off periods, fork‑in‑the‑road clauses and sovereign immunity frequently arise. Usage and practice are broadly consistent across England & Wales, Scotland, Northern Ireland and Ireland, where domestic courts mainly address recognition, enforcement and interim measures. Investment treaty arbitration contrasts with commercial arbitration (between private parties) and sports arbitration. EU law has limited intra‑EU investment arbitrations; the UK’s position differs post‑Brexit.

English Commercial Court refuses permission to amend to add s 67 BIT challenge as time-barred under AA 1996 s 73; nationality arguable but for lack of reasonable diligence.

The Czech Republic v Diag Human SE and another [2024] EWHC 708 (Comm) What are the practical implications of this case? The judgment offers practical guidance on how the ‘reasonable diligence’ condition in AA 1996, s 73(1) operates. It warns parties in arbitration to remain vigilant to unfolding factual matters that may demand further enquiry, in order to satisfy the ‘reasonable diligence’ requirement and maintain an arguable case that is not rendered time-barred under AA 1996, s 73(1). It also emphasises the elevated duty of care owed by investment arbitration practitioners when advising clients in arbitral proceedings, so as to avoid claims of insufficient diligence in the conduct of jurisdictional challenges before the tribunal. What was the background? ...

Investor–State Arbitration at a Crossroads: Honduras Leaves ICSID, Ecuador Moves to Rejoin, EU Investment Court Proposals and UNCITRAL Reforms Drive Global Debate on Investment Protection and FDI

Honduras rejects the ICSID Convention In recent weeks, Honduras announced it would repudiate the international treaty under which it consented to submit disputes to the World Bank’s International Centre for Settlement of Investment Disputes (ICSD), better known as the ICSID Convention. The move followed the country being hit last year with nine distinct ICSID claims, among them a politically charged action brought by a US-based developer seeking up to US$10.7bn in compensation. Honduras now mirrors three other Latin American states that have denounced the ICSID Convention: Ecuador, Bolivia and Venezuela. Across Europe, parliament have also been keen to jettison investment arbitration in favour of a new investor court, promising reforms they believe could rebalance a regime that critics often say tilts towards investors. India, South Africa and New Zealand have likewise taken steps in recent years to curb their exposure to investor–state disputes, so at first sight it may seem these Latin American moves are part of a worldwide revolt against investor–state arbitration. Yet that impression would overlook a...

UNCITRAL Arbitration Rules: practitioner overview of ad hoc and investor-State cases - 1976 and 2010 frameworks, Transparency and Expedited Rules, appointing authority/PCA role, procedure, awards and costs

This Practice Note provides an introduction to the overall structure of the United Nations Commission on International Trade Law Arbitration Rules (the UNCITRAL Rules). The UNCITRAL Rules occupy a significant role in contemporary arbitration practice. They are crafted for ad hoc international commercial arbitrations—proceedings not administered by an arbitral institution and, typically, not conducted under that institution’s rules. The Rules may likewise be employed in investor–state arbitrations commenced under a treaty, such as a bilateral investment treaty, where the treaty permits arbitration conducted under those rules. Unless the parties stipulate otherwise, the UNCITRAL Rules govern arbitration agreements concluded on or after 15 August 2010, ie the date the revised Rules took effect. The earlier 1976 UNCITRAL Rules continue to apply to all arbitration agreements entered into before that date. Both the 1976 and 2010 UNCITRAL Rules are separate from UNCITRAL’s Model Law on International Commercial Arbitration, adopted in 1985 and revised in 2006, which has been adopted (often with modifications) by more than 50 jurisdictions—see Practice Note: The UNCITRAL...

Overview of the SCC Arbitration Institute: Secretariat, Board, Rules (2023), Model Clauses, and UNCITRAL Procedures

What is the SCC? The Stockholm Chamber of Commerce Arbitration Institute (SCC) sits within, yet operates autonomously from, the Stockholm Chamber of Commerce. The Institute was founded in 1917. In the 1970s, the United States and the Soviet Union recognised the SCC as a neutral centre for resolving trade disputes. As a result, it remains a preferred venue for East/West cases, that is, disputes involving one or more parties from North America or Europe and one or more parties from Russia, China, or states of the former Commonwealth of Independent States (CIS). Over the past 25 years, filings at the SCC have grown substantially, and the institution has become one of the most important and most frequently used arbitration institutions globally. The SCC’s latest statistics can be found on its website (see also Practice Note: Arbitration statistics and surveys). The SCC manages a wide range of domestic and international commercial arbitration matters and is also a well‑recognised forum for bilateral investment treaty disputes. Around 50% of SCC...
